Discovery of tetrasubstituted imidazolines as potent and selective neuropeptide Y Y5 receptor antagonists: reduced human ether-a-go-go related gene potassium …
A series of novel imidazoline derivatives was synthesized and evaluated as neuropeptide Y (NPY) Y5 receptor antagonists. Optimization of previously reported imidazoline leads, 1a and 1b, was attempted by introduction of substituents at the 5-position on the imidazoline ring and modification of the bis (4-fluorphenyl) moiety. A number of potent derivatives without human ether-a-go-go related gene potassium channel (hERG) activity were ...
